基于CBR与RBR的设备采购决策支持系统

Equipment Purchase Decision Support System Based on Case-Based Reasoning and Rule-Based Reasoning

该文通过分析制造行业新产品试制部门的设备采购过程,说明采购决策支持系统引入的必要性,并基于CBR(Case-BasedReasoning)案例推理和RBR(Rule-BasedReasoning)规则推理,构造了混合框架的推理系统及相应的案例表示结构,解决了设备采购等复杂决策领域中决策支持系统冗余推理的问题。最后将该混合推理框架及案例表示结构应用于某大型制造企业试制部门的决策支持系统中,取得了较好的效果。

The equipment purchase process of technique and production prototype workshops in the manufacturing en-terprises is analyzed in this paper.Based on case-based reasoning and rule-based reasoning with new viewpoints,an ar-chitecture is presented.Moreover,the framework of the purchase decision support system and the case presentation are put forward.The architecture is evaluated within a decision support system of technique and production prototype work-shops' equipment purchase.
